OPENNESS TO TRADE AND INDUSTRY COST DISPERSION: EVIDENCE FROM A PANEL OF ITALIAN FIRMS*

ABSTRACT We use Italian firm‐level data to investigate the impact of trade openness on the distribution of firms across marginal cost levels. In so doing, we implement a procedure that allows us to control not only for the standard transmission bias identified in firm‐level TFP regressions but also for the omitted price bias due to imperfect competition. We find that more open industries are characterized by a smaller dispersion of costs across active firms. Moreover, in those industries the average cost is also smaller.     

The Roman quarries at Antinoopolis (Egypt): development and techniques

The aim of this research was the survey and the study of the many quarries located in the first spurs of the Gebel el-’Adila, close to Antinoopolis (Middle Egypt). These quarries are an excellent opportunity for observation and research concerning the “landscape archives” and preserve traces of man’s activity, representing a real cultural heritage. The paper gives a short geological setting of the area and reports our recent study (2006 onward) on traces, typologies, methods and development of the quarrying activity in the area, focussing on the Roman period. The working traces allowed us to define the working tools used for quarrying, the organisation of the works and of the quarry exploitation, as in the area many remains of the quarry organisation network are extant or recognisable, such as: service posts, sledge-ways, docks.     

The search for historical experience

In the first part of my paper I will try to reconstruct a series of attempts at dialogue between history and the social sciences made by historians connected with the “Annales” (Marc Bloch, Ernest Labrousse, Giovanni Levi, Bernard Lepetit). What these attempts have in common is the idea that in history, as in the natural sciences, it is to some extent possible to carry out forms of experimentation on the sources, and that the inclusion of history among the human sciences, and even the scientific future of the discipline itself, ultimately depend on the adoption of this method. In the second part I will discuss the relationship that links historical experimentation with lived experience, and I will conclude by discussing the possible meaning of the idea of experimenting with the sources of history.     

Effects of Soil Characterization on the Seismic Input

This paper is aimed at determining the effects of the soil characterization on the seismic input to use for seismic assessment. Three different soil profiles have been assembled to represent the stratigraphies found through a proper experimental investigation, carefully described, and alternative seismic site response analyses have been performed. The surface spectra obtained from the seismic site response analysis (SRA) are very different from each other, thus evidencing the importance of carefully describing soil stratigraphy. Furthermore, the comparison among the surface records found for different return periods has shown a limited sensitivity of the SRA to the seismic intensity.     

Crack Patterns Induced by Foundation Settlements: Integrated Analysis on a Renaissance Masonry Palace in Italy

This study presents some numerical results related to the analysis of the structural damage of a historic masonry building, Palazzo Gulinelli, in Ferrara, Italy. A detailed analysis of the inhomogeneities of the facade, historic documentation, and recent restoration interventions carried out in an adjacent building, suggest that the Palace underwent various modifications both on the structural configuration and on the borne loads. Such modifications might be the main cause of some differential settlements and of the consequent significant crack pattern on the load-bearing walls. Therefore, in the present paper the occurrence of a crack pattern on the facade is simulated by carrying out standard linear and non-linear finite element (FE) homogenized models; differential settlements are applied in order to reproduce the structural changes occurred over time. Previous experiences of the authors (for example, Acito and Milani in 2012 and Mallardo et al. in 2008), the current crack pattern of the building (of its facade in particular) and the monitoring data referring to some of them are the main references for the analysis carried out. The structural survey, the numerical results, and the data monitoring suggest two main conclusions: 1) a good correlation between numerical results and monitoring data is assessed, therefore the cracks can be reasonably related to past differential settlements; and 2) the cracks/damage that occurred as a consequence of differential foundation settlements reduce the ability of the facade to resist seismic actions.     

Spatial Effects of Labour Policies Promoted in Italy from 1996 to 2006: An Analysis in the EU Context

One of the most important economic and social facts concerning the European Union consists in the mismatch among its regions in terms of unemployment rates. The paper aims at examining and measuring the efficiency of Italian policies for labour market carried out in the last 10 years, in terms of reduction in the regional disparities in comparison with the whole European distribution of unemployment. We question whether these policies have been successful or the territorial dimension has still a relevant role on the unemployment in Italy. We try to answer to this question by calculating the Theil Index using data from 1996 to 2006 on unemployment and participation from Eurostat at NUTS 2 level, comparing Italian data with those of other EU countries. Our results show that Italy has still a prominent role in the geographical disparities among regions and that its contribution to the geographical concentration of unemployment is still high (especially if we consider female and youth unemployment).     

Multi-technique investigation of historical Chinese dyestuffs used in Ningxia carpets

In this article, an extensive work is presented concerning the characterization with both chromatographic (high-performance liquid chromatography) and spectroscopic (surface-enhanced Raman spectroscopy and visible reflectance spectroscopy) techniques of historical Chinese dyestuffs in several carpets, mostly coming from the Ningxia region in Northern China and dating to the seventeenth–nineteenth centuries. Notably, the color of the background of these fine artifacts has been an object of debate since, while being depicted as bright red in the ancient iconography, nowadays it appears as orange/yellow. Therefore, in addition to the identification of all the colorants used in the carpets, the present study investigated the reasons of this apparent inconsistency, pointing out an explanation based on the joined use of the yellow dye obtained from the pagoda tree and a “fugitive” dye obtained from brazilwood.
